Speciati'on of Letters Patent.

Patented May 9, 1922n serial No. 509,522.

A drive shaft i' is mounted in hearings at one end ot the machine traine and provided with a driving pulley 8 and with eeeentries Si having` straps Connections l() with the lovver )ortion of the shoe on eac-h side, so that when the shaft is revolveth an oseillating' motion will he imparted to the shoe. ln the shoe a loner impert'orate plate 11 is provided, extending from end to end of the shoe. Above this impertorate` plate are plates l2 and 13 alternating in position to the top ot' the shoe, the lower plate projecting` in adranee of the next upper one and the plates 'l2 lie-ing; allshoifter than the plates 12% and as the plates 1'2 are all grouped at thn forward portion o't' the. shoe1 an unobstructed spaee provided hetiveen the rear portions ot the plates 13. Each oi the plates l2 and 13 has groups of perforations 'llat the torivard portion thereot extending aeross the shoe from side to side, the pertorations o'lE the lower plates being in :1dvanee ot' those above and eaeh plate having an iniperforate area in the rear ot the per- Forated section. le prefer to make some the separating plates shorter than the others, piet'erahly the alternate filetes, for eeonomgr or material and to reduce the Weight ot' the shoe.

Ahove the upper plate is a hopper 15 provided ivith a slide l@ For regulatingr the delivery ot' grain upon the ivnpertoifate portion ot the upper plete. U the rear of the .shoe is a spout i? adapted to receive the splverieal seeds, sueh as Wild peas, and direet them into a reeeptaele 1S beneath. In this niaehine. as in our former patent, advantage is taken ot' the ditl'erenee in shape he' Teen vwild peas and kernels ot grain. sueh t :is ivlieat. Vllhen the `train eontaining wild peas is discharged Ytrom the hopper upon the` upper plate of the shom the spherieal wild peas will roll down the plate toward ihe lower dise-barge end thereof, while the irotion of the shoe .vill Cause the kernels of wheat to he ted toward the upper end of the shoe.

The pertorate sections are arranged in stepped relation in the 'forward portion of the plates and when the mixture ot peas and grain rearhes one of these sections. a considv'ahle quantity4 will tall through the perforation?. ivhieh have the funetiou of spreading and thinning the material as it is discharged upon the imperforate section of the plate next beneath. Some of the Wheat. kernels Will pass forward over the pertorations and over the 'forward end oi the plate and from thence drop upon the projecting end of the plate next beneath, but a considerable quantity of the ,grain will flow through the groups of perforations with the Wild peas, and as the mixture strikes the plato next beneath, a 'further separation ot the peas and grain will take place, the grain being spread out trom side to side ot the plate in such a manner that the peas will be allowed to roll by gravity to the lowerl discharge end of the plate, while the wheat, through the oscillation of the shoe. will again begin to climb the plate to the pertorations therein. Some of the peas carried along will How through the perforations ot the second plate and another separation will take place in the plate beneath and so on from the top to the bottom of the shoe, the perforations spreading the mixture throughout the full width of the shoe, a considerable quantity ot' the peas being released while the grain is fed up to the perforations Aforming the initial separation, and a second separation taking' place when the peas and grain fall through the pertoratious upon the impertorate Section of the plate beneath.

The rear end of each plate is provided with a grain. kernel arrester consisting of a narrow plate 2l) having holes 2l therein through Whirh the ivilrl peas may be discharged. The collecting' oF the Wild peas in trent of these arrester plates will serve to retard any o'f the grain kernels which may have approached these plates and the flow ot' the wild peas through the perforations in the plate will tend to turn the ,grain kernels crosswise of the openings and prevent their discharge with the peas, and the continued oscillation ot the shoe will work the `grain upwardly on the plates toward the pertorations therein.

This machine is adapted for a ,'roup or multiple of shoes, one arranged. above the other, but where this construction is eniployed, it is hardly practicable for lack of space to provide a hopper such as shown in Figure l between ear-h adjacent shoe. le therefore arrange a feed Chute 22. as shown in Figures 8 and 9, with a spout leading theretrom for delivering,T the material upon an imperforate plate 24s, the steps or terru- ,qations therein harinar the eltect ot' feeding the material 'forwardly as the shoe osrillates. so that the mixture ol' peas and grain will be positively fed toward the upper end ol the plate. At the forward end of this plate a perforated section 25 is provided. through which the Wild peas tall upon an imper'forate plate beneath for deliveriY to a pea chute 1T at the rear end ot the shoe. AV spreader 26 is preferably provided in connection with this form of delivery spout to aid in distributing the grain evenly across the plate. A bolt 28 pivotally connects the spreader with the perforate plate 25 on each side of the machine. A bar 29 is interposed between the rails of the spreader near the apex thereof and a bolt 30 is connected with this bar 29 and is operated by means of a rod 3l having a crank connection 32 with the lower end of the rod 30. By this means the end of the spreader may be raised or loW ered to regulate the feed of grain beneath it.

The side rails operate to deflect the grain toward the sides of the separating plate and of course if the spreader is raised a considerable distance above the plate, the grain will flow readily beneath it. The operator, noting the character of the feed, can easily and quickly adjust the spreader, causing the material to be evenly distributed from side to side of the separating surfaces. In other respects the method of separation is sub stantially the same as shown and described with reference to the other figures.

ln the operation of the machine, the mixture of wild peas and wheat is delivered upon the upper plate of the shoe and spread out in a thin sheet from side to side. The spherical Wild peas Will begin to roll down over this plate, aided by the oscillating movement of the shoe, which keeps the grain iu motion and allows the spherical seeds to work through any body of grain which may tend to retard the movement of the peas toward the lower end of the plate. Vhile this gravity .separation is taking place, the ma` trrial is fed upwardly toward the perforated section of the plate and When this section is reached, the peas and a considerable fpuintity of the grain Will fall through the holes in a thin stream. extending from side to side of the plate.` and drop upon the im )en forato section of the plate beneath. ere the .separation above described Will be repeated while the grain is being fed upwardly on the second plate to the perforated section thereof. Upon reaching this section, a con siderable portion of the material will fall through and be spread out in a thin sheet on the plate beneath and this operation `.vill continue to the bottom of the shoe, each delirery of the material from one plate to another sori'inp; to spread out and thin the sheet ol grain, so that the Wild peas can become easilyY separated therefrom by gravityv and when the bottom of the shoe is reached. a practically complete separation will be made. B v increasing the number of separating plates, the capacity of the machine may, oi course, be greatly increased, and there may be a number of shoes arranged one above the other in the same machine, all performing` the same separating operation.

ln various ways the details of construction herein shown and described may be modified and etill he within the scope ot our invention.

Thilo ne have slur-Mii und desrribeil thirv' machine as adopted 'tor use in separating wild pero; from grain. it will be underetood that it may be utilized wherever :i Seperation is to be made between elongated |find spherical seeds or material,
